GFJRG'E BEHEER@ G1 MILWUKEE, 'WISCONS To @ZZ -w/lwm t may conoce/zz.'

Be it known that l. inoRGn BERNERT, a citizen of the United States. ancl residentof in' waukee, in the county of liiilwaulu-:e und State of lVisconsin, have inventefl4 cetein new and useful improvements in Pneumatic Grain-Elevators; und. i (lo heiehj.' declare *that the following o Juil, clear, and exact desciiption theieof.

My invention is directed to new and usefui improvements in pneumatic means foi' ele- Voting g'fain.

Purticulailv in View of its conditioning effect upon gi'ein the pneumatic method of elevating groin is very ciesiralole, but e consiclerablev disadvantage hcretofoie encountered in methods of pneumatic elevating has been the excessive amouni. of power requiiecl to elevate the groin When it is discharged intothe convoi/ei' trunk in advance of the ian', and in such instances as when the groin is discharged into the fun an unclesileol` breakage of the groin occurs together With e consioeicable Weail on the fon necessitating #frequent replacement of parte.

it is thei'efore the primary objet of my invention to provide an arrangement for feeding vgroin into a pneumotic conveyor trunk Wheiehy seid grain may be elevated by the air in the #funk with a minimum eX- penclituie of power.

have found that o. relatively great amount of power consumed in carrying groin ovein a bend in the conveyor tiuni, this amount of power being in proportion to the suele of the bend. l have also found that itis impractical to feee12 guaio. directly into e vertically disposed'conveyeir-tiunlfz, in View of the excessivoliting loeol imparted to the :mass ci oir at that side of the con;v

Weyer trunk at which the pjiain is admitted.

it is therefore more specilicalll 'the object of my invention to provide an arrangement for introducing grain into a pneumatic elevating tiunk in such menne? es: to inifolve a minimum loss of'powe: due 'to changing the direction of `he trunk, und yet in ouch manM ner es to pioificie foi a piepen distribution of the grain tra Teisely oi the trunk: wherecy the initial Lifting lour'iinpereci io the column of in the tiunlz; is clistrihutefl hroughcut the tieiisverse eiea of the tiunli'.

Essentially invention consists in in troducing giain into an upw'aifll inclineri coni/eyeiq tiuni poition n obtuse to Specification of Letters Patent.

,ee-meteo epe. ee, ieie Application ilei func i5, 3.92.7. Serial No. Wfl-,829.

mein portion of the trunk, whereby an oh- 'tuse bend is provide-Ci in the trunk which consumes comparatively little of the conveying power of the column of auf and fui'ther whereby the vertical lrwitty-cuused 1novement of the `ruin traverses the receiving trunk portion whereby to distribute the gi-ain hy gravity throughout thc entire transi Voyer trunk portion 8 disposed also at an ecute .ongle to the horizontal plone, and this second conveyer trunk portion is merged into a vertical trunk portion 9.

rlhe inclined trunk portions 6 and 8 are provided in their top Walls with inlet openings 10. about which are fitted the discharge boots l of gi'ain eeiiing mechanisms 12 prefeialoly of 13 adopted to be opened upon pressure of groin thereupon Wheeloy to prevent leakage oi ehe conveying column of llt will, however, he appreciated that any suitable feeding'ineens be employed which. prevents leakage of eil'. it will he furti er appreciated that the feeding mechanisms may he ariengeoi in any desire manner to pio cure elscheige through the openings 10, and it is observed that lf ligues, two embodiments of my invention adaptecl foi' introducing groin into the ele 'Voting duct adjacent the fan7 and for introducing into the elevating (luci: at en inten mediate Jpoint the-rect, and that these modi iicetions may he used together or singly.

es shown more paiticuleily 'by the orows, the-direction of the movement of the grain, uncle? the influence of gravity when disc longed into the trunk, traveises sail tiunl. upper jpf'ution of the inclined section fi or 8 o ti if the ciu-rent ,of aiiv in Seial gioie-ion he tenui; is not sucienty that type including valve gates Thus. the ein falls into the.

n introducing groin into :i vertieaily fiisposed trunk, the giet/ity impeied movement of 'the grain is pareille-i to the (iiieetion of movement of that section oi the oir 'ouizeiit at theeicie et 'which the genio is intiodueed. Tous the gravity load of said section off curro vt being not euioient to impeto am upm/eid conveying .movement to the gioie? seid wiii continue to foil vertieaiiy, ood the fe maining sections of the oir euient will not te utilized5 Thus to insure the conveying .movemei'it of thegein, :in excessive expenditure of power iieoeesiteted. lo die* charging grain into the horizont-ei section of the conveyor twink, the Current of ai? properly takes up the conveying load of the groin, but o eoneequeilt iight engelen 'eend moet be mede to proeuie eiemting mot/ef .ment of the gieiii.
